A non-specific immune response (also called immunity) is antigen-independent while a<span> specific immune response is antigen-dependent. The examples of the non-specific immunity are fever, phagocytosis by macrophages, skin and mucus. The example of the specific immune response is c</span>ytotoxic T-cells able to recognize antigens on infected cells and kill them before the infection could spread. So, the first line of defence is the non-specific immune response. However, if pathogens pass that line of defence, the specific immune response activates.
Answer: Like with fingerprints, no two people have the same brain anatomy, a study has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences.
Explanation: An example is the heart's circulatory system, where the vessel supplying blood to the posterior part, known as posterior descendant artery, stems from the right coronary artery in 80-85% of the cases, and from the left coronary artery in the remaining 15-20%. This is known as either right of left dominance
Answer:
Pressure gradients, the rotation of the earth, and friction are three primary variables that influence the wind. Atmospheric pressure gradients are the ultimate source of wind. The wind blows from high-pressure zones to low-pressure areas.

For most activities it usually lasts at least 90 seconds in duration for you to solely rely with lactic acid. <span>The ultimate energy fuel is adenosine triphosphate (ATP), which is produced in the cell. Lactic acid in the cell will itself metabolize into ATP, a process by which energy can be produced without oxygen, known as the anaerobic lactic energy system. </span>
Another difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a mono-pole force, while electrostatics is a dipole force.
